You are on your heels and the bar is pretty much behind the midfoot every rep. You might need to bend over a hair more and sooner.
The most concerning problem to me is the height of your elbows. They're jacked WAYYYYYY too far up. This is because you have a rounded upper back. Think big, king kong chest. Pin your elbows to your sides. A narrow grip would probably be useful here, too.
You're also slamming into the bottom. Dominate the weight. Don't let it dominate you. Get tighter and control the weight down a little bit.
I also would love to know why you're doing 8's then 2's then a single. What program are you running? Are you programming yourself?
